I have no idea how to set this data in an API and send these values using Ldap extended operation/controls. If any one can give me little idea how to start i.e. which API to be used , will be very helpful.
I have the option of using any of the LDAP SDK (novell, unboundid or JNDI etc...)

I am just told that I need to develop a client which has to invoke the extended operation( defined by the server viz. modifySS ). So do I need to get the implementation of these API's from the server team. I am confused.
